Description

A kind of method of producing the algae of the biological effect that tool improved
The present invention relates to produce the method for the algae of the biological effect that has improved.
From period in time immemorial, the mankind just are used as nutrient and food with algae.The people in the Far East are the main forces of consumption algae; But recently, developed country also uses the algae that does solid form or tablet.Algae is the carrier with high nutritive value, because do the necessary material of healthy life that the algae of solid form contains high concentration, for example, the compound of vitamin, protein, albumen micro element, sugar part, polyunsaturated fatty acids etc.
Recently, the environmental pollution problem that become international.Today, toxic heavy metal (as, lead, mercury, cadmium, copper) and carcinogenic substance (as the polynuclear aromatic compound that concentrates) pollution of ocean be can not be ignored.It is a difficult problem that these materials accumulate in the marine alga body.By ocean " complete marine alga " that obtain or that under other natural endowment, breed, can not be used for human or animal's nutrient, food, cosmetics and medicine; Having only in advance, some components of " the complete marine alga " after biologically harmful substance has been removed in purification are only available.One of this class method of purification is referring to Carames de Guovea " Cosmetics and Toiletries " 95,47(1980).Yet, purification is decomposed a part of biological active ingredients, and therefore, the biological value of the algae component that is obtained reduces (Zajic:Properties and Products of algae:Edition Planum significantly, New York, (1970)).
Therefore, preparation is not subjected to the no Homonemeae of environmental pollution gradually important.
The more known method that artificial culture algae are arranged for example, in the basin under sunlight, or is cultivated algae under natural illumination or artificial lighting or unglazed photograph condition in the enclosure space that guarantees aseptic condition.
According to No. the 5696690th, Japanese publication, marine alga is used in the cultivation of algae, aseptic seawater, and artificial lighting contains the solution of various nutrient salt.
According to No. the 45 17146, Japanese publication, the industrialization of unicellular green chlorella is cultivated and is to use aseptic fresh water medium and finishes under the condition of getting rid of carbonic acid gas and illumination.
The cultivation that French Patent (FRP) also discloses unicellular green algate of fresh water No. 2103462, its industrialized cultivation are to use the nutrient solution that contains suitable nutrient salt to realize in photosynthetic mode.
According to Hungary's publication the 4613/84th and No. 4614/84, the cultivation of algae is in the mineral water at natural origin, medical water or the heat supply water, or in their mixture, and add metallic compound to 10 -2The concentration of mole/L realizes.
In any known method, be used to make all artificial production under aseptic condition of algae of food, feed or medicine.In these methods, the result that condition caused who cultivates algae is that the character of the algae of obtaining is similar to the algae that grows under the natural endowment of non-environmental-pollution; Or because the mode difference of artificial culture makes the character of the algae of obtaining poor slightly.
By the algae of the method artificial culture of prior art, if contain several elements, as selenium, zinc and silver, also trace just.
Be known that selenium has the various biological function, referring to Thressa etal Nutrition Review 35,7(1977), Shamberger.J.of Env.Path.and Tox.4,305(1980), Masukawa et al.Experientia 39,405(1983).What also know is, selenium has the effect that brings high blood pressure down, and improves the ischaemic of heart, the state of the low and infraction of oxygen content, and the wax lipofuscinization (Ceroidal lipofuscinosis) that suppresses central nervous system; Selenium also has the effect of improvement to periodontitis, reduces cancered possibility; In addition, selenium also is considered to a kind of sudden change inhibitor.Also certifiedly be, scarce selenium can cause multiple disease, for example, hepatonecrosis, myonecrosis, the erythrocyte film rupture, the ST in the electrocardiogram raises, kwashiorkor syndrome and multiple sclerosis.
The beneficial effect of selenium mainly is based on its effect that activates glutathione peroxidase, and this enzyme is that important interior the giving birth to of suppressing harmful peroxidating process suppressed son.As the indispensable composition of gst enzyme prothetic group, selenium is one of most important indispensable material in the life, and selenium does not gather in vivo, therefore will constantly replenish.Until today, also can only pass through inorganic compound (selenium dioxide, sodium selenite etc.) selenium is introduced in the organism.
The objective of the invention is to provide the algae of the special biological property of tool, and, because increasing of Se content can guarantee the biological effect of selenium.
The present invention is based on such understanding, promptly under certain condition, algae can not only survive (just not dying) in containing the solution of selenium, and can also grow, thereby, can in the nutritive solution that contains high concentration selenium, cultivate.This is wonderful understanding, because prior art thinks that algae can be killed by the selenium of toxicity.Moreover the present invention also is based on the recognition, that is, selenium is incorporated in containing under a certain condition in the algae bio body of cultivating in the seleno culture medium.
Therefore, the present invention relates to prepare the method for the algae of the biological effect that tool improved, wherein, the selected algae that goes out is under aseptic condition, in the medium that contains fresh water and nutrient salt, under the situation that has carbonic acid gas and light to exist, cultivate in photosynthetic mode, perhaps, under no optical condition, also containing carbon, nitrogen, hydrogen is cultivated in the medium of oxygen, then, separate the algae of being obtained.According to the present invention, inorganic or (with) organically selenium compound is with 10 -7To 2 * 10 -3The concentration of mol is added in the medium, and then, inoculation can be mixed the pure culture of the algae of selenium on medium.The acquisition methods of this pure culture is, selected algae is inoculated in the liquid nutrient medium, and this medium contains inorganic (also can contain organically) nutrient component, handles with N-methyl-N '-nitro-N-nitrosoguanidine then.In the single algae of being obtained by sudden change, select in the time of in containing seleno culture medium, cultivating and can mix selenium, and identical with the wild strain at least algae of growth rate.Behind the pure culture inoculation medium that obtains like this, through the nurturing period, isolate algae, be dried to optimum moisture content if desired, again, make it to decompose with known ultrasonic method or Ginding process.
According to the present invention, the pure culture that can mix the algae of selenium preferably prepares from monoplast green alga or blue algae, as chlorella (Chlorellasp), grid algae (Scenedesmus sp.) and spirulina (Spirulina sp.), concrete grammar are, after handling with N-methyl-N '-nitro-N-nitrosoguanidine, carefully cell is come out, be distributed in a series of solid culture mediums, these medium are made through dilution, and to have replenished concentration be 10 -7To 2 * 10 -3The selenium compound of mol.In the algae of being turned out, select ramp and the most preferred strain that can mix selenium again, further cultivate with liquid nutrient medium, the pure algae culture that obtains like this be can be used for industrial.
Like this, at growing period, selenium is incorporated in the algae bio body by above-mentioned processing, and the original algae of its concentration average specific exceeds 10 4Doubly.
Cultivate in the medium of the algae can mix selenium in industrialization, with distilled water as liquid.In this class medium, except the nutriment of routine, also replenish with inorganic or (with) organic selenium compound.Inoculum so preparation and the culture medium inoculated algae through sterilizing, the promptly aforesaid kind that can mix selenium.In its process of growth, algae is taken in selenium in its organism, and does not have the above-described toxic pollutant of not expecting.
The algae of so preparation is isolated from medium, use known method, under temperate condition,, the highlyest be no more than 80 ℃, carry out drying with 65 ℃ of the suitableeest temperature.Dried algae is with grinding the particle that suitably is decomposed into about 1 micron size.In addition, wet algae concentrate also can decompose through ultrasonic processing, then with above-mentioned condition drying.
What obtain like this is that selenium content is the algae powder of 250-400 μ g/g, it can directly be employed or consume, or be used for food, in feed and the cosmetics, or use with medicine and biological active agents, or (with) as the additive of these materials, its form can be any commercial form of these products, preferably tablet, capsule or other formulations.
The major advantage of the inventive method can be summarized as follows:
A) algae can also be cultivated with easy equipment by the method that cheapness is easily gone.
B) do not need purifying and the rapid post processing of multistep after the cultivation.
C) algae is cultivated down in aseptic condition, has got rid of environmental pollution, thereby, there is no doubt that the algae of such acquisition can be by the human consumption.
D) it is higher and have the biology that improved and an algae of physiological effect to access the selenium content that has than existing algae.
E) according to algae that the inventive method obtained widely (and preferably) be applied to nutriment, cosmetics, medicine and other field.
The most preferred application of algae that obtains according to the inventive method is the treatment field, because selenium is the activator of glutathione peroxidase prothetic group.Selenium is not assembled in vivo, uses the algae that the inventive method obtained then can Selenium Supplement, thereby makes owing to lack the caused various Health cost of selenium and all can obtain medical treatment.
Following non-limiting instance is understood the present invention in more detail.
